The hydride ion affinity (HIA) is a measure of carbocation stability. The difference in HIA for a secondary allylic carbocation and a tertiary allylic carbocation is 12 kcal/mol. Assuming that this is also the difference in the energies of the transition state for the carbocation formations, estimate the rate difference.
